Mine would have to be OH GOD .... Excellent! I havent seen any other movies about God but that one is quite good!
What Dreams May Come/Film synopsis After Chris Nielsen (Robin Williams) dies in a car accident, he is guided through the afterlife by his spirit guide, Albert (Cuba Gooding Jr.). His new world is beautiful and can be whatever Chris imagines. Even his children are there. But, when his wife, Annie (Annabella Sciorra), commits suicide and is sent to hell, Chris ignores Albert's warnings and journeys there to save her. Upon arrival, Chris finds that rescuing Annie will be more difficult than he'd imagined.
Not precisely on topic, more with the afterlife and a more Eastern view of the universe and its workings. It would be, "The Art of Racing in the Rain". Life, death and the interplay between. Narrated with insights by,...... their dog.
